Atlantic salmon and sea trout display synchronised smolt migration relative to linked environmental cues
Harvey, Alison C.; Glover, Kevin; Wennevik, Vidar; Skaala, Øystein (Journal article; Peer reviewed, 2020)Anadromous salmon and sea trout smolts face challenging migrations from freshwater to the marine environment characterised by high mortality. Therefore, the timing of smolt migration is likely to be critical for survival. ... -
Chromosome aberrations in pressureinduced triploid Atlantic salmon
Glover, Kevin; Harvey, Alison C.; Hansen, Tom Johnny; Fjelldal, Per Gunnar; Besnier, Francois; Bos, J.B.; Ayllon, Fernando; Taggart, John B.; Solberg, Monica Favnebøe (Journal article; Peer reviewed, 2020)Background Triploid organisms have three sets of chromosomes. In Atlantic salmon, hydrostatic pressure treatment of newly fertilized eggs has been extensively used to produce triploids which are functionally sterile due ... -
Disentangling the effects of sex, life history and genetic background in Atlantic salmon: growth, heart and liver under common garden conditions
Perry, William Bernard; Solberg, Monica Favnebøe; Brodie, Christopher; Medina, Angela C.; Pillay, Kirthana G.; Egerton, Anna; Harvey, Alison C.; Creer, Simon; Llewellyn, Martin; Taylor, Martin I.; Carvalho, Gary R.; Glover, Kevin (Journal article; Peer reviewed, 2020)Livestock domestication has long been a part of agriculture, estimated to have first occurred approximately 10 000 years ago. Despite the plethora of traits studied, there is little understanding of the possible impacts ... -
DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
Kaland, Håvard; Harvey, Alison C.; Skaala, Øystein; Wennevik, Vidar; Besnier, Francois; Andersen-Fjeldheim, Per Tommy; Knutar, Sofie; Andersen-Fjeldheim, Kaja Christine; Glover, Kevin Alan (Journal article; Peer reviewed, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions?
Harvey, Alison C.; Juleff, Gareth; Carvalho, Gary R.; Taylor, Martin I.; Solberg, Monica Favnebøe; Creer, Simon; Dyrhovden, Lise; Matre, Ivar Helge; Glover, Kevin (Peer reviewed; Journal article, 2016-07)The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may ... -
Domestication-induced reduction in eye size revealed in multiple common garden experiments: The case of Atlantic salmon (Salmo salar L.)
Perry, William Bernard; Kaufmann, Joshka; Solberg, Monica Favnebøe; Brodie, Christopher; Coral Medina, Angela Maria; Pillay, Kirthana; Egerton, Anna; Harvey, Alison C.; Phillips, Karl P.; Coughlan, Jamie; Egan, Fintan; Grealis, Ronan; Hutton, Steve; Leseur, Floriane; Ryan, Sarah; Poole, Russell; Rogan, Gerard; Ryder, Elizabeth; Schaal, Patrick; Waters, Catherine; Wynne, Robert; Taylor, Martin I.; Prodöhl, Paulo; Creer, Simon; Llewellyn, Martin; McGinnity, Philip; Carvalho, Gary R.; Glover, Kevin Alan (Journal article; Peer reviewed, 2021)Domestication leads to changes in traits that are under directional selection in breeding programmes, though unintentional changes in nonproduction traits can also arise. In offspring of escaping fish and any hybrid progeny, ... -
Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface
Besnier, Francois; Solberg, Monica Favnebøe; Harvey, Alison C.; Carvalho, Gary R.; Bekkevold, Dorte; Taylor, Martin I.; Creer, Simon; Nielsen, Einar Eg; Skaala, Øystein; Ayllon, Fernando; Dahle, Geir; Glover, Kevin (Journal article; Peer reviewed, 2020)Background Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental ... -
A genetic method to infer ploidy and aberrant inheritance in triploid organisms
Delaval, Aurelien Nicolas; Glover, Kevin Alan; Solberg, Monica Favnebøe; Taggart, John B.; Besnier, Francois; Sørvik, Anne Grete Eide; Øyro, Johanne; Garnes-Gutvik, Sofie Nordaune; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Harvey, Alison C. (Journal article; Peer reviewed, 2024)Polyploidy occurs naturally across eukaryotic lineages and has been harnessed in the domestication of many crops and vertebrates. In aquaculture, triploidy can be induced as a biocontainment strategy, as it creates a ... -
Implications for introgression: Has selection for fast growth altered the size threshold for precocious male maturation in domesticated Atlantic salmon?
Harvey, Alison C.; Skilbrei, Ove Tommy; Besnier, Francois; Solberg, Monica Favnebøe; Sørvik, Anne Grete Eide; Glover, Kevin (Peer reviewed; Journal article, 2018-12-18)Background: Mature male parr (MMP) represent an important alternative life-history strategy in Atlantic salmon populations. Previous studies indicate that the maturation size threshold for male parr varies among wild ... -
